STATES PATENT OFFICE. A

HOWARD M. BARBER, OF STONINGTON, CONNECTICUT, ASSIGNOR T0 C. B. COTTBELL 6t SONS COMPANY,- OF NEW YORK, N. Y., A CORPORATION OF DIELAVARE.v

Be it known that I, HOWARD MrBARBER, a citizen of the United States,-and resident of 'stonin'gton, in the county ii New London and State i 'hhsve inventeds new and useful provement in fille t Get:

this and Folding Machines, of which the fol ow! is a scoifiestlon, The e jest of his invention is teprovide ans wh y the speed at continu usly moving groups of sheets may be abruptly retarded and'the groups of sheets folded oil at'a surface speed less than the speed of heretofore produced where the foldingtravel of the web as=it passes through the press and into the cutting and folding machine.

In sheet cutting and folding machines as mechanism operated "at the Speed of the ress, theoutput of the press was materially limited by the inability ofthe folding mechanism toact sucoessfull at ='as--*high' a speed as the press was capab e ofvoperating the speed-Jot the press" being thereby necessarily tied down to the highest efiicient speed of the folding-mechanism -1By. myinvention,

a folding mechanism operating at a lesser I speed than that of the press can be used in conjunction with the press without add1- tional strain on the folding mechanism thereby omitting the runnin of theprss at a muc higher rate of'spee than heretofore possible. 1

' A practical embodiment of my invention is represented in the accompanying drawin s, in whichi a 1' re'l is a section adjacent to the near side rame of so much of a cutting and fold a ing machine as embodies my invention, Fig.

21s a diagrammatic section taken from front to rear intermediate-the'side frames {is a'section taken adjacent to the i frame. and Fig. 4 is a detail view shown Fig., 8

the

parts. I r The web, as it sees from the press, not shown herein is ed between the rollers 1., 2, and irom thence downwardly between the pair of coacting rotaig cutters 8 4, mounted uides 7, direct the web to the collecting cylinder 9 mounted on the shaft 10., whic collecting cylinder is herein shown as provided with three sets riving connection between sever at side snss'r cu'r'rmc AND roLnms macnms.

T ey Hider 1 's 9 r o dlsd with sheet spr ng pushers is, 18, 20, tor aiding the leading edges oi the sheets into he grl 'ppers ll, 1 13, ot the collecting cylinder -A.curved gu de 21 is, prgvided around the'under side of the first transfer cylinder-'15." The sec? ond transfer cylinder 22 is mounted on a shaft 23 and is'plrovided with n single set of grippers 24. he'-male 'folding cylindcr 25 is mounted on the'sha ft'26 and 15 pro vided-"with two sets of gripper-s27,- 28, and I two folding blades 29, N -curved guide -31 'arrangedaround a "portion of the under side of the male folding cylinder 25.

The female folding cylinder 32 is mounted on a shaft33 and 1S provided'with two sets of folding laws 34,355,, arranged to coact with the to dinghlades'29," 30: A curveduide 86 extends partwayaround one side of t 1e female folding"cylinder'32'. Thedeliv-- and is provided with two sets of-grippers ery cylinder 37 "is mounted on'a shaft 38 (sipectiVeI 'and deliver them into a suitable ehvery device, such, for-instance,- as a,

pocketed delivery partway 'aroun 41. A guide 342 extends one side of the delivery l cylinder 37. i If so desired one or more slitters l3 maybe providedarranged' to coact with 'the delivery cylinder 37 --for slitting-the I sheets lengthwise lof *thei ritra'vel intoa plu-. rality of sections before they arefdelivered o the delive device 41.

The severe inechanismsare'drivenfrom the press, not shpwn, "throughithe gear 44,

as follows: The'c'ylinders 22, 25, 32and537 are driven at a surface speed about onehalf the speed of the web through the gears 5, 45, 4:7, $8.; The collecting cylinder; 9 and first transfer cylinder 15 are driven ata surface speed twice; that of the cylinders 22, 25, 32, and 39, through the gears 49, 50, 51, 62, and the rotary cutter are,dr-iven through the gears 53, 54s The web feed rolls 1 and 2 are driven through the gears 56, 56', 57. It will thus be seen that the re tary cutters are driven two revolutions for each revolution of the first transfer cylinder 15 and the collecting cylinder is driven one and one-third revolutions for each revo-' 'cylinder 22. This is necessary to prevent the pushers 18 from marking the sheet next to the cylinder 15 after the group of sheets has been transferred to the cylinder 22. The

spring pushers 19 and 20 may be fastened in fixed positions tothe surface of. the cylinder 15 and stand out a sufficient distance beyond its periphery to force the leading edges of the sheets over against the surface of the collecting cylinder 9 and into the respective grippers thereon. It is to be understood that these pushers .19 and 2( never pass or drag over the printed portions of any of the sheets and it is therefore unnecessary to mount them on rocl: shafts. A fixed cam 59 is arranged in position to suecessively open the grippers on the collecting c linder 9 for receiving the sheets. A movable cam controlled by a box cam 61, is arranged to successively open the grippers of the collecting cylinder every one and onethird revolution of thecollecting cylinder for transferring the sheets to the first transfer cylinder 15. Fixed cams 62, 63, are arran ed in position to operate the grippers 17 or receiving the sheets from the collecting cylinder and transferring the sheets to the second tranfer cylinder. A fixed cam 64 is arranged in position to operate the grippers as of the econd transfer cyl1nder 22 for transferring the roup of sheets from the cylinder 15 to the olding cylinder 25. Fixed earns 65, 66, are arranged in po sition to operate the grippers 27, 28, to re ceive the sheets from t e second transfer cylinder and to release the sheets at the time of the folding operation. Fixed cams 67, 68, 69, of well known and approved form rovided for floating and openin the fold mg fjaw 84, 85, to receive the s esta from the olding cylinder 25 and transfer themes the delivery cylinder 37. Fixed cams 70, 71, are rovided for operating the gr ppersee of t e deliver? cy inder or receivin He folded sheets .roi-n the folding cylin and dglivrifig he same to the delivery 7.

vice e1.

In operation: The web as it comer the prespasses downwardly bet cutters 8, 4, where it is cut trans into sheets. The collecting cylinder 9 collects three sheets and transfers them together with the fourth sheet everyone and one-third revolutions of the collecting cylinder 9 to the grippers 17 of the first transfer cylinder 15. The group of sheets is then transferred from the grippers 17 on the cylinder 15 to the grippers 24 on the cylinder 22 which transference will cause the abrupt retardation of the sheets. As the sheets are at the under side of the cylinder 15. when they are transferred to the cylinder 22, the sheets will fall away from the surface of the cylinder onto the guide 21 and will not be disturbed by the more rapidly moving cylinder 15 after the control of the group of sheets has been assumed by the cylinder 22. The grippers 24 will, in turn, transfer the sheets to either the grippers 27 or 28 of the folding-cylinder 25 at the surface speed of the said folding cylinder. The group of sheets will then be folded off to the cylinder 32 and transferred therefrom to the delivery cylinder 37 where the folded group of sheets may be slit lengthwise of its travel into a plurality of sections and then delivered to the delivery device 41. i

By the term cylinder as used in the description, I contemplate any suitable means for passing the sheets and signatures through the prescribed path and by the term grippers I wish to include any engaging devices suitable for the purpose of leading the sheets or signatures through said prescri'bed path.

It is evidentthat various changes may be resorted to in the construction, form and arrangement of the various parts without departing from the spirit and scope of my invention; and hence I do not wish to limit myself strictly to the form herein shown and described, but
